The present invention relates to a magazine for a hand firearm, which is detachably mountable to the weapon, incorporating a drum-like, approximately cylindrical housing (10) which accommodates a greater number of cartridges in an orientation parallel to the axis of the housing, further incorporating an approximately spiral-shaped divider device (9), which is located inside the housing and accommodates the cartridges, a driver plate (14), which is adapted for indexed rotation about its axis and is driven by the force of a spring, said driver plate causing the cartridges to advance to the next position on a spiral path after each shot, and a follower (18) disposed in said magazine, which causes the cartridges to advance on their spiral path, to exit said divider device and to enter into a magazine head (21). In accordance with the invention, there is provided that the entire follower moves behind the last cartridge stored in the magazine on the spiral feeding path through the divider device, that said follower is not connected solidly to the driver plate but radially displaceably instead, and that said follower glides radially outward in a guide of the driver plate while being forwarded. In this way, the follower is prevented from jamming and trouble-free operation is ensured.
